Hi,
In my research I'm using Marble's reagent for chemical etching of this alloys, which contains: 50ml(H2O)+50ml(HCl)+10g(CuSO4). Some examples of my results (metallographic and AFM) you can find on my website http://www.republika.pl/bramowicz/.
I just wanted to draw your attention to the fact, that in austetnitic state - alloys etch hard, but in martensitic state I have good results.

Best regards
Mirek
